West Nile Virus

April showers bring May flowers - not to mention great breeding sites for mosquitoes that can carry West Nile Virus.

Now is the time for everyone to eliminate standing water from around their homes so that mosquitoes won't have the upper hand this season.

"The County's annual mosquito control initiatives are currently underway," said County Executive Andy Spano. "Catch basin larviciding, organized mosquito breeding ground clean-up events and public education campaigns are a few of the things that we are doing. However, these activities alone are not enough. It is important that residents do their part to help us fight West Nile virus," he said.


"The combined efforts of residents and county government over the past few years have been successful in curbing the mosquito population, keeping human cases of West Nile virus extremely low and eliminating the need to spray pesticides," continued Spano. "For Westchester to continue to have low West Nile virus activity this season, people must take steps to eliminate potential mosquito breeding sites around their homes and neighborhoods and report the location of standing water that is not easily eliminated.

On May 7, certified technicians from the Westchester County Department of Health began applying briquettes of the larvicide Altosid (methoprene) into state, county and local municipal catch basins as part of its effort to prevent the spread of West Nile virus. Additionally, on a case-by-case basis, the control agents Vectolex CG, Vectobac G and Bactimos Briquettes may also be used. The larviciding process begins with municipal storm water catch basins in the northern area of the county and proceeds south until all of the county's municipal catch basins have been completed.

On June 8 & 9, residents can participate in the county's "Spring S.T.I.N.G. Clean-Up" event which is an organized effort to fight West Nile virus by ridding Westchester's communities of potential mosquito breeding sites. The "Spring S.T.I.N.G. Clean-Up" event is an excellent opportunity for residents to get involved and take pride in their communities while, at the same time, helping to stop the spread of West Nile virus. Old tires, which are popular mosquito breeding sites, can be brought to Westchester Community College for recycling on June 8, from 1:00 pm to 3:00pm and June 9, from 9:00 am to 3:00 pm, during the County's Household Chemical Clean-Up weekend. Old tires are also accepted year-round at the County's tire recycling reception centers.

Mosquitoes capable of carrying West Nile virus lay their eggs in stagnant water. The eggs can develop in any pool or puddle of water that stands undisturbed for more than four days. Mosquitoes will breed in any untreated water, so the Health Department recommends doing the following around your home:
